The "Dismantling Ideological Policies for Semiconductors and Science Act" aims to significantly alter the landscape of federal science and technology funding by repealing specific provisions from the CHIPS Act of 2022 and the Research and Development, Competition, and Innovation Act. The bill's stated purpose is to ensure federal efforts in the semiconductor industry and STEM workforce prioritize speed and leverage all talent without regard to race, color, ethnicity, sex, or sexual orientation. It asserts that programs related to Diversity, Equity, and Inclusion (DEI) are discriminatory, divisive, and detract from core objectives, thus necessitating their removal to restore original legislative intent.

Title I of the bill focuses on repealing and modifying numerous DEI-related requirements across various federal STEM programs. This includes eliminating the National Science Foundation's Chief Diversity Officer position, programs for research supporting DEI in STEM, and DEI activities in higher education. It also removes requirements for recruiting STEM educators that advance DEI, diversity considerations in STEM research capacity programs, and mandates for data collection on faculty demographics and DEI best practices in the STEM workforce. While preserving support for Historically Black Colleges and Universities (HBCUs) and Tribal Colleges or Universities (TCUs), the bill explicitly removes "race-based activities" and broader "Minority Serving Institutions" (MSI) references.

Furthermore, the bill modifies outreach requirements for fellowship programs and amends NSF scholarship criteria to focus on addressing STEM workforce gaps rather than specific diversity metrics. It repeals provisions related to opportunity and inclusion, educational outreach for underrepresented communities, and equity requirements in initiatives like clean energy technology competitions and cleaner airplane development. These changes collectively aim to remove what the bill identifies as ideological policies from federal science and technology funding frameworks.

Title II introduces limitations on federal mandates, prohibiting agencies from imposing non-statutory mandates on entities seeking federal funds. These prohibited mandates include policies related to prioritizing diverse hiring, training, and retention, similar to those outlined in Executive Order 14035. Agencies would also be barred from requiring policies on employee childcare, wraparound services, community investment plans, environmental impact minimization, climate change or environmental justice mitigation, project labor agreements, or consultation with local labor organizations.
